Image Steganography with Dual Layer Security Using Fragment and Unite Technique

Abstract

At the present time where a regularly increasing number of data is made in different structures, kept and transferred, online security is the most vigorous factor. Different ways such as Cryptography, Steganography and Digital Watermarking are used to defend the data. The proposed framework gives additional dual layer of security as Cryptography and Steganography have been combined. Here data will be encrypted by using Encryption Algorithm AES. Then the encrypted data is embedded into a system’s Defaulting image using least significant byte LSB Algorithm. Steganographed Default image is then fragmented into uniform parts and gets unite into reverse sequence using Uniform Fragment and Unite Technique. Reverse Steganographed Default image is then hidden (unseen) into another image. The proposed framework has summarized the goal to be safety and security factors.
